Refractory Corrosion During Steelmaking Operations
2013 (English)In: Treatise on Process Metallurgy, Elsevier, 2013, Vol. 2, 283-303 p.Chapter in book (Refereed)
Refractory corrosion during steelmaking operations is a complex phenomenon involving not only chemical wear but also physical/mechanical wear (such as erosion/abrasion) processes which may act synergistically. To understand the corrosion mechanisms, the following should all be examined together-refractory microstructure, melt properties, and their wetting and interaction at high temperatures. In this chapter, the corrosion mechanisms between solid refractories and liquid melts (slag or metal) will be discussed. The refractory corrosion test methods will be briefly summarized. The main focus is on the discussion of tar-bonded oxide refractories, which are widely used in steelmaking practice, and their corrosion mechanism. Local corrosion of refractories at the slag-metal interface is one of the important factors shortening the service life of the refractory during the steelmaking processes. The Marangoni effect plays an important role in the local refractory corrosion at the slag-metal interface.
